1983 oldsmobile 98 emissions control system delete tutorial pt. 1 of 3 

The only removal video for the emissions I could find……thanks a lot !

Thank you for sharing your under hood view of your Ninety Eight. I had the 1984 version with the same powertrain. I remember AIR stood for Air Injection Reactor. My system used the air pump to supply mildly pressurized air to my exhaust ports during warm-up to promote oxidation. Then the system switched the air to the catalytic convertor to oxidize hydrocarbons after warm-up. The plastic valve assembly diverted the air to the air cleaner on deceleration to prevent blowing the catalyst apart. I simply found a shorter belt size to drive my accessories and removed my air pump. The metal reed valves at the upper ends of the steel tubes stayed in place. I merely rubber capped them. The steel nipple on the catalytic convertor end was easy to crimp closed with stout locking pliers. I kept my EGR system to reduce pinging, though running fairly advanced factory timing. My average mpg was 19 when my electronic carburetor was stuck lean. It dropped to around 16 mpg after the carburetor was returned to normal and under ECM mixture control. Running the carb full rich (ECM disconnected) yielded about 13 mpg. I sold my 98 some time after my speedometer broke at about 268,000 miles. Wonderful, simple, inexpensive to own car. May yours be a pleasure to drive for many years.

Thank god, I finally found a video that actually shows you what to take off! My son bought a 1981 delta 88 and this is similar setup.

Those things that are hooked to the manifolds are air injection tubes you should take those off and put brass plugs in them also those weird things are called aircheck valves they only flow one way it doesn't pull air from the Cadillac converter it pumps air into the Cadillac converter you're doing a good job

Great videos, its gonna help me out alot when i delete it.

This video helps me out a lot

I have a 1980 oldsmobile delta 88,and when i purchased the car most of that stuff your talking about was removed .Even the Ac bracket,lines and compressor.Which i replaced the air conditioning bracket ,compressor and brought that smog pump delete bracket and change the wide belt pully wheel that came with it to a v belt narrow(four season 45955 ) pully wheel.Which when i pull off the smog pump delete wheel it gives enough slack to remove the compressor belt without loosing up the ac bracket bolts.Dorman make a smog pump delete bracket not sure of the part number.

Will this apply for a 260? I took off all the smog stuff but having a hard time finding information on rerouting the hoses to the carb. Never worked a two barrel, switching to 4 later but for now just keep the 2 to drive. I pulled off the ported vacuum switch, do I need it?

Would you like to sell that smog pump, mine squeals like hell

So you cant delete if running stock transmission stock carb???

4:40 I thought you could get plugs that screw into each cylinder where the tube comes out of? Instead of having that ugly bit that comes out above the manifold?

i also have a 83 olds 98.

I have an 87 Cadillac with the 307. What carburetor did you replace it with? I’ll be deleteing my smog also since I’ll be replacing my busted head gasket.

I have an 87 oldsmobile custom cruiser and the misfortune of living in California.
